Echoes of Eternity (Infinity and Chaos Saga Book 3)

Something is calling humanity into the dark.
It sounds like home.

When AJ Edgars touched the artifact, a Voice woke in his blood and named him something he still doesn't understand: heir of Adam. Now it's calling him outward — past the edge of every map, toward worlds that fell silent a million years ago.
He follows aboard the Wayfinder , a warship rebuilt to carry scientists instead of soldiers: a crew of scientists and military chasing a signal into the deep dark. His father fears where it leads. His father is right.

Because every dead world tells the same story. A people who heard a call to something vast and radiant. A people who answered. A people who were devoured for answering — by a hunger old beyond reckoning, one that wears the voice of everything you love and has fed on the faith of civilizations since before humanity first looked up and wondered.

Now it has found the Wayfinder . Cut off from Earth, no way home and nowhere to run, AJ must learn to tell the true Voice from the one that only sounds like it — before the whisper unmakes his crew from the inside, one gentle certainty at a time.
The lost reached for the light and were swallowed.

Humanity is reaching too. The only question left is whether anything reaches back.
